Since Chrome version of the tests updated from 98 to 99, my deferred scripts are showing as render blocking, but only on Chrome. Firefox is fine for example.
We didn’t change any code in the site or Cloudflare config, so the only difference is the version of Chrome - and since then, there’s a flash block parsing the html, showing only half of the top menu, and when the rest of the menu is parsed, it detects as CLS.
Do you guys have any idea why this is happening?
